The Astro AI AM33D Multimeter is designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. It's easy and safe to operate and features many different functions for measuring current, voltage, and resistance, as well as continuity, transistor, and diode testing, which is both for automotive and household uses. Use this multimeter for: household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more. Note: 1. When the Meter is working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken because there is a danger of electric shock. 2. Before using the Meter, inspect the exterior casing. Do not use the Meter if it is damaged or if all or part of the exterior casing is removed. Look for cracks or missing plastic. Pay special attention to the insulation around the connectors. 3. If you have mistakenly connected the red test lead to the 500mA selection, then used this meter to test larger current(like 10A) or higher voltage, it might probably burn out the wires even the meter. 4. If you are the beginner, you should have known some basic physical concepts and basic methods of using a meter, you also should have read the user manual carefully and kn...

The meter will burn if connected wrong.) Note: If the meter is used as voltmeter, it is suggested that the yellow wire and black wire are connected together. Note: If the current cannot display properly, please check whether...

Do It All, and Then Some The Etekcity MSR-R500 Digital Multimeter is a practical tool for electricians, hobbyists, and general household use.

The INNOVA 3320 is a Auto-Ranging Multimeter designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. It's auto-ranging scales eliminate the need to dial in the correct range when making electronic measurements. The 10 MegOhm input is safe for automotive and household uses (i.e., household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more). The color-coded LEDs allow you to quickly check household batteries (green = good, yellow = weak and red = replace). Includes attachable test leads, holders and stand for hands free use and features protective rubber corner guards for drop protection. The INNOVA 3320 has a single setting resistance function for AC and DC voltage.

This meter is used for single-phase power with one hot line and one neutral line. If you want to measure the circuit with 2 hot lines, you will need 2 meters, one for each line. Main Specifications: Working voltage: 80 ~ 260VAC Working frequency: 50/60Hz Measuring:Accuracy: 1% Power Consumption: 0.2W Measurement speed: 2 times/s Operating Temperature Range: 14℉~140℉/-10℃~60℃ Store data when power off The blue backlight can be turned on/off manually Test Range and Display format: 1.Power: test range: 0~22kW < 1kW, display: 0.0~999.9W 1kW~10kW, display: 1000~9999W > 10kW, display: 10~22kW 2.Energy: test range: 0~9999kWh 10kWh, display: 10~9999kWh 3.Voltage: test range: 80~260V(single-phase) Display: 80~260V 4.Current: test range: 0~100A Display: 0.00~99.99A Precautions 1. Please make sure the AC input is Pure Sine Wave.(Municipal electric power is pure sine wave). Please don't use the meter to measure AC power converterd from a DC-AC inverter UNLESS you can make sure the output from your DC-AC inverter is Pure Sine Wave. This is very importatnt. 2. Applied load should not exceed the rated power. 3. Wiring order can not be wrong. 4. This module is suitable for indoor, please do not use outdoor. Packing including: 1x 80 ~ 260VAC 100A Power Mult...
